For parties or buffets, a 1½- to 2-quart size works well for dips and snacks.
On the other hand, moisture gathers in a slow cooker as it works. To allow that to cook off, or to thicken the cooking juices, take the lid off during the last half hour of cooking time.
Of course, if you sense that the food in your cooker is drying out, or browning excessively before it finishes cooking, you may want to add ½ cup of warm liquid to the cooker.
One more thing – a slow cooker provides a wonderful alternative if your oven is full – no matter the season.
For example, chicken can overcook in a slow cooker. Especially boneless, skinless breasts. But legs and thighs aren’t immune either. Once they go past the falling-off-the-bone stage, they are prone to move on to deeply dry.
Cooked pasta and sour cream do best if added late in the cooking process, ideally 10 minutes before the end of the cooking time if the cooker is on high; 30 minutes before the end of the cooking time if it’s on low.
If you’re going to exceed that limit, pull out your second slow cooker (what – you have only one?!) and divide the contents between them.
